Research On Script-driven Based RBC Functional Testing Method

Based on the demands of China's railway development at present and in the future, in view of the successful practice of the European ETCS, the Ministry of Railways proposed the Chinese Train Control System (CTCS). Now, the CTCS-3train control system has been put into service on several300km/h high speed lines..The Radio Block Centre (RBC) is one of the key equipment of CTCS-3train control system, so to ensure that the RBC system meets the System Requirements Specification (SRS) is of great significance for guaranting safety of railway. Before putting the RBC system into service, it is necessary to carry out a complete testing. Due to the complex logic of the RBC system, to design and develop a practical functional testing method becomes necessary. Currently, the study of RBC functional testing has just been started in China, therefore the research at present stage is import and innovative.This thesis focuses on the research of script-driven based RBC functional testing method. Firstly, the functional requirements of the RBC system are analyzed; secondly, based on the functional requirements, the architecture for the RBC functional testing platform is proposed, the structure and the function of each module are also described; then, the method of how to extract features from the CTCS-3System Requirements Specification and the Overall Technical Solution, and the method of how to design test cases for each feature are discussed; thirdly, the algorithm and measures of building test sub sequences from test cases are introduced, and a Ant Colony Algorithm based method for genearating test sequences are described in detail; finally, focusing on the RBC functional testing platform, the detailed design and implementation are elaborated. In the end of the thesis, a testing on a RBC simulator is carried out to verify the feasibility of the RBC testing method proposed in this thesis.
